In the proposed method, the combined modal story shear and torque profiles are computed for each direction of excitation (x and y) and then using SRSS (Square Roots of Sum of Squares) combination rule, combined modal story shear and torque due to simultaneous excitation of x and y directions are calculated. The proposed load pattern is derived from the resulted combined modal story shear and torque profiles, so only a single-run pushover analysis is required for simultaneous excitation of x and y directions. In this procedure, the contribution of the higher and torsional modes and the frequency content of a specific ground motion are considered. The proposed method is evaluated through an asymmetric-plan building under different ground motion records. The results are compared to those obtained from nonlinear time history analysis and establish the accuracy of the proposed method in estimation of the structural responses.
